STRAW-BURNING STOVE.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed February 21, 1908 SerialNo. 417,100.

To all whom it may concern:

Be it known that I, HENRY O. RUGGLES, a citizen of the United States, and a resident of Moro, in the county of Sherman and State of Oregon, have invented a new and Im roved Straw-Burning Stove, of which the fo owing is a full, clear, and exact description.

This invention relates to stoves, and especially to stoves for burning a highly combustible substance such as hay or straw.

The object of the invention is to produce a stove of this class which is simple in construction, and which is provided with improved means for insuring a good draft and for controlling the draft.

A further object of the invention is to construct the stove so as to facilitate the heating of water within the same.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding arts in both figures.

Figure 1 is a vertical central section through a stove constructed according to my invention; this view is taken on the line 11 of Fig. 2; and Fig. 2 is a plan of the stove shown in Fig. 1, the stove pipe above the stove being shown in cross section.

Referring more particularly to the parts, 1 re resents the base of the stove, which is of substantially rectangular or box form. At its forward side upon the base 1 there is mounted a cylindrical stove body or shell 2, in which the combustible, such as the straw 3, is placed. The up er end or head 4 of the shell 2 is formed wit a charging opening 5 which is closed by a suitable cover or lid 6 which rotates about a tubular vent 7 which extends upwardly from the head near one side of the shell as shown. To the upper end of the vent pipe 7 an elbow 8 is attached, which connects with the main stove pipe or flue 9, the horizontal portion of the said elbow being rovided with a damper 10 to regulate the raft through the vent.

The shell or body 2 is rovided with a bottom 11 which is elevate as shown, so as to form a combustion chamber 12 beneath the shell. This combustion chamber is formed above the cover 13 of the base or box 1, and beneath this cover 13 a water space or water back 14 is formed, the said water back being supplied with water from the sides of the base by means of a suitable pipe 15. The forward portion of the cover 13 is cut away so as to form an opening 16 through which the combustion chamber 12 is placed incommunication with the interior of the box 1. At the rear side the base or box 1 is provided with an opening 17 over which seats the main flue or stove pipe 9. The arrangement is such that this stove pipe or flue 9 extends vertically u ward at the side of the body 2, as indicate At an intermediate point in the length of the stove pipe 9 a damper 18 is provided for controlling the upward draft through the pipe.

At the rear portion of the base 1 a return bend or elbow 19 is provided, which effects communication from a draft opening 20 in the back of the stove body 2 with the rear portion of the combustion chamber 12. O posite the opening 20 the forward side of tile shell 2 is provided with an openin 21 in which there is placed a removable s aft or stick 22. The inner extremity of this stick or shaft lies substantially in the opening 20, as indicated in Fig. 1. It should be understood that when the stove is being charged, this stick is allowed to remain in the osition shown, and the straw or hay is packe tightly into the body 2 of the stove. The shaft 22 is then withdrawn at the front so that a draft opening or bore is formed through the lower part of the hay between the o enings 20 and 21. After the hay is ignited t e draft can be very nicely controlled by the dampers 10 and 18. In this way the combustible is made to burn slowly. The flame which passes out of the body 2 and through the elbow 19, passes through the combustion chamber 12 and thence toward the rear under the water back 14. In this way the water in the water back is thoroughly heated by the gases of combustion before they pass u the flue 9.

In practice, there wi be two cylinders or stove bodies 2, and one will be kept burning while the other can be refilled. This arrangement is especially useful where the fire must be kept burning continuously.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A stove of the class described having a body with a draft opening in the wall thereof, said body having a second draft opening opposite said first opening, a flue with which said second opening communicates, and a removable shaft adapted to lie in said openings when said body 1s packed with the combustible, and adapted to be withdrawn to form a draft vent through the combustible. 5 2. A stove of the class described having a base with a water back under the cover thereof, a body supported on said base, means for directing the gases of combustion from said body across said cover above and below the 10 same, and throughv said base, and means for carrying oh. the said. gases from. said base.

3. Astovecomprising a base, abody sup- .orted thereu. on and having an elevated ottom, said ase having a cover with a combustion from said body across the upper side of sai'd water back and across the under side thereof through said base, a flue leading the gases up from said base, and a connection betiween saidflue and the upper part of said b0 Iii testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
